开始定义状态f[i][j][k]为[i,j)区间插入k个括号,使用记忆化搜索,但是成功爆栈,得到4个mle #include <bits/stdc++.h> using namespace std; const int maxn = 45; int n, k, len; long long f[maxn][maxn][maxn]; char str[maxn]; int trans(int l, int r){ int x = 0; for(int i = l; i <= r; i++)…
Given a non-empty array of digits representing a non-negative integer, plus one to the integer. The digits are stored such that the most significant digit is at the head of the list, and each element in the array contain a single digit. You may assum…
题意 You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numb…
